This is the fourth edition of CSA C22.2 No. 208, Fire alarm and signal cable. It supersedes the previous editions published in 2014, 2003, and 1986. It is one in a series of Standards issued under Part II of the Canadian Electrical Code.
The main changes to this edition are the following:
a) inclusion of new requirements for Type FAS cables rated for direct burial/wet locations;
b) addition of equivalent metric sizes of conductors;
c) addition of optional markings and applicable requirements for sunlight resistant, direct burial, and halogen-free characteristics; and
d) addition of missing 150 °C thermoplastic and 105 °C thermoset columns in Tables 4 and 5.
This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.
This Standard was prepared by the Subcommittee on Control, Instrument, Communication, and Marine Cables, under the jurisdiction of the Technical Committee on Wiring Products and the Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the Technical Committee.
This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
This Standard applies to single- and multiple-conductor fire alarm and signal cables with a maximum nominal voltage rating of 300 V and a minimum temperature rating of 60 °C for use in buildings and other structures in dry, damp, or wet locations in accordance with the Canadian Electrical Code, Part I.
Because other CSA Group Standards specify requirements for certain constructions suitable for use as fire alarm and signal cable, this Standard does not cover all such constructions.
The designations for constructions covered by this Standard use the letters FAS followed, for constructions rated above 60 °C, by the temperature rating. The type designations are as follows:
b) FAS 90;
c) FAS 105;
d) FAS 150; and
e) FAS 200.
In this Standard, shall is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; should is used to express a recommendation or that which is advised but not required; and may is used to express an option or that which is permissible within the limits of the standard.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.
Notes to tables and figures are considered part of the table or figure and may be written as requirements.
Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
